I found a 97 with and auto (was looking for a 5 speed) and I think I can get it cheap. What pump does it have? thanks

 

180 HP

 

The pump is depowered from the manual version a little bit but at least it has the larger delivery valves that the older 12V autos don't have. Some 370hp injectors should more than offset the smaller pump size.

 

What is the difference in the pumps? or is it in the injectors?

 

The injectors are different and the pumps are quite a bit different between the two. A 180 pump is simply not a depowered 215 pump. There are several internal parts that are different between the two.

 

and the smaller pump generally wont make the HP that the 215 HP version will. Now, who wants to trade me a 215 for my 180??

 

The internal parts difference cause the depowering.

Do you know what would the 180's limit is? I was under the impression it is more than almost anyone non-commercial here would make, say for instance 800+rwhp.

 

Helix, plungers, cam--stuff like that. You can take a little pump and get FLOW out of it, but it won't ever flow like a 215.

I just swapped out my 160 for a 215 and they are light years different. Top to bottom--in the middle, all-the-way different. Same plate (slid way BACK), same inj/turbo/timing/DV's. UNREAL different.

Junkyard special.

 

About how much do those 215 pumps run?

 

Without some extensive tweaking (read: you are better off to buy a 215 or a performance pump) I think enough fuel for 800HP would be next to impossible to get out of a 180 pump.

As Wade said there are a few significant internal parts differences in the 215 that are not shared with any other pump. It is unique when comparing it to the other three pumps that were offered on our Dodges.

 

So where would the point be that it becomes a restriction to further hp progress?

 

Find a 215 and sell your 180 to a 160 guy, in some ways I like a 215 over a race pump but the flow isn't there, a 180 pump is good to about 550 with Twins using 370's, EDM's will add to that.

I paid $500 for my junkyard special. Runs perfect.

Reman/exchange is around 1300.

Specialty shop hot rod is closer to 3000.

Way back when, Joe D made 533 with a 215. The only thing done to the pump was in the governor section. Plate/springs/timing. NO DV's or twiddling up front.

 

I just called Piers with a couple of questions and the guy I spoke to said there is no difference between the 180 and 215 pump. He said the difference is in the injectors.

 

Hmmm... I know the newer 180s have DVs that are closer but I just can't imagine it being the exact same. He must have meant the same body for the P-7100 is used but not the same internals!?
